Comparative Example 1

[0257]Evaluations were made in the same manner as in Example 1, except that the type and proportion of pigments used for the preparation of pigment dispersion liquids, the type and amount of the epoxy compound, the type of the initiator, and the proportions of these components were changed as listed in Table 1. The addition amount change of the epoxy resin was adjusted by changing the addition amount of the alkali soluble resin. The evaluation results are shown in Table 1.

Abstract

A colored curable composition for a solid-state image pickup device, including a polyhalogenated zinc phthalocyanine pigment, a photopolymerization initiator, a polymerizable compound, and an epoxy compound.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 USC 119 from Japanese Patent Application No. 2009-065053 filed on Mar. 17, 2009, the disclosure of which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a colored curable composition suitable for making a color filter for a solid-state image pickup device such as a CCD or CMOS, a color filter obtained using the colored curable composition, and a method for producing the color filter.[0004]2. Description of the Related Art[0005]Color filters are essential components of solid-state image pickup devices. As a composition for a color filter, a negative type curable composition including a pigment dispersion liquid, an alkali soluble resin, a photopolymerizable monomer, and a photopolymerization initiator has been proposed (see, for example, Japanese Patent Application Laid-Open (JP-A) No. 2-199403). In recent years, color filt...
